The Braddock Locks and Dam Hydroelectric Project is in the pre-construction phase at one of nine US Army Corps of Engineers navigation structures that comprise the Monongahela River System, authorized by Congress to provide year-round navigation on the Monongahela River between Pittsburgh, Pennsylvania, and Fairmont, West Virginia. The project is located in the Borough of West Mifflin and the City of Duquesne, Pennsylvania.

The locks and dam were constructed between 1902 and 1906 and originally named Monongahela Dam 2. The facility underwent a reconstruction that ended in 1953, and was consequently demolished and replaced in 2004, renamed as the Braddock Locks and Dam. The Braddock Pool is maintained above the Braddock Project for 12.6 miles, while the Emsworth Pool begins immediately downstream of the Braddock Project, extending for 11.2 miles. The Braddock Project is the first dam on the Monongahela River, and is located 11.2 river miles of upstream of the confluence of the Monongahela and Allegheny Rivers.

The Braddock Project is comprised of a gated dam, a land-side lock, and a river-side lock and is located at river mile 11.2 of the Monongahela River (Figure 1). In 2004, the fixed crest dam was replaced with a gated dam. The hydroelectric project will be constructed on the south side of the river and will operate as a run-of-river facility in order to maintain a near-constant upper pool, to maintain navigational purposes on the Monongahela River. The Braddock Hydroelectric Project was issued a Federal Energy Regulatory Commission (FERC) original license as Project No. 13739-002 on June 4, 2015 and is expected to be completed and become operational in 2026.
